KeyError: np.uint32(50000)

KeyError: np.uint32(50000)

Hello, when I was using the Python inference pipeline for detection and tracking, an error "KeyError: np.uint32(50000)" occurred.
The specific situation is shown in the screenshot below.
This is the same whether I'm using the driving_sample dataset or the pedestrians dataset.
The SDK I'm using is version 4.6.2, the Python environment is version 3.9, and the PyTorch is the CPU version.
Could you please tell me how to solve this problem?
